Better homes start with better building systems.
HiPer Haus designs, installs and commissions MVHR ventilation systems, carries out blower door airtightness testing, and supplies CO₂ heat pump hot water for high-performance and Passive House homes across South Australia.
Specialist services for high-performance homes
Every service is focused on building systems that make a measurable difference — to comfort, air quality and energy use.
MVHR Design & Installation
Whole-home mechanical ventilation with heat recovery — designed from first principles for your building, installed by specialists, commissioned and balanced before handover.
Blower Door Testing
Precise airtightness measurement using calibrated equipment. We locate air leakage paths, provide written reports for Passive House certification and NCC compliance, and support remediation.
Heat Pump Hot Water
CO₂ heat pump hot water for all-electric, solar-powered and high-performance homes. Efficient in all weather, solar-compatible, and a clean replacement for gas storage systems.
Builder & Designer Support
Specialist technical support for Passive House and high-performance projects — from MVHR coordination and airtightness strategy at design stage through to commissioning and handover.
The building systems inside your home matter as much as the structure.
A well-insulated, airtight home needs controlled ventilation — without it, moisture, CO₂ and pollutants accumulate. The right systems, properly designed and commissioned, transform a good building into a home that is genuinely healthy and comfortable to live in.
- Indoor air quality — Continuous, filtered fresh air in every room. No stale zones, no humidity spikes — just a consistent, healthy indoor environment year-round.
- Thermal comfort — Stable temperatures without cold spots or draughts. Proper ventilation and airtightness eliminate the discomfort that insulation alone can't fix.
- Energy efficiency — MVHR recovers up to 90% of heat from outgoing air. Heat pump hot water uses a fraction of a conventional element. Both reduce ongoing running costs significantly.
- Moisture & condensation control — Balanced ventilation keeps relative humidity in check, protecting the building fabric and reducing the risk of mould, condensation and long-term structural damage.
- Long-term building performance — Systems that are properly designed, installed and commissioned perform reliably for decades — not just on paper at handover.
Designed for demanding projects.
Whether you’re targeting Passive House certification, an architect-designed high-performance home, or a retrofit to reduce energy use — we understand what these projects actually require. We’re engaged from design stage, not called in at the end.
- Passive House MVHR design and certification support
- Airtightness strategy from early design stage
- Blower door testing at mid-construction and final
- MVHR ductwork coordination with your builder
- Full commissioning, balancing and documentation
Projects we’re proud of.
High Performance Home — Wynn Vale
Working with Enduro Builders, we installed a Zehnder ComfoAir Q350 MVHR system with ComfoTube ducting run within a Pro Clima Intello airtight dropped ceiling — keeping all ductwork inside the thermal envelope. We also supplied and installed a Reclaim Energy CO₂ heat pump hot water system.
Zehnder Q350 MVHR commissioned and balanced. Reclaim Energy CO₂ heat pump supplied and installed.
High Performance Home — Middleton
A high-performance home on the Fleurieu Peninsula built by 35 Degrees South in 2025. HiPer Haus designed and installed the Sabik MVHR system to deliver controlled fresh air ventilation throughout the home.
Sabik MVHR unit designed, supplied and commissioned. Built by 35 Degrees South, 2025.
Passivhaus — Theberton
A Certified Passivhaus built by Enduro Builders in 2025. HiPer Haus supplied and commissioned the Zehnder ComfoAir Q350 MVHR system and Reclaim Energy CO₂ heat pump hot water system with 315L tank.
Zehnder ComfoAir Q350 MVHR and Reclaim Energy CO₂ heat pump with 315L tank supplied and commissioned.
Passivhaus Plus Display Home — Mount Barker
Designed and built by Enduro Builders to demonstrate that a Certified Passivhaus can be achieved in Australia using locally available materials — without importing windows. Opened to the public as a display home. HiPer Haus supplied and commissioned the MVHR and CO₂ heat pump systems.
Certified Passivhaus Plus. Zehnder ComfoAir Q350 and Reclaim Energy 315L CO₂ heat pump supplied and commissioned.
